One of the most dangerous entities to lurk in the twinkling swamps, the shel, a creature that appears as an eyeless, pale, human child, is a hunter that relishes the chase more than the kill. Moving erratically, limbs bending in ways that seem unnatural, the shel will quickly approach its target, leaping on and viciously biting and scratching.
Should the shel become severely wounded, its head will rotate, transforming it into the cacoshel, an enormous beast comprised mostly of razor-sharp claws and many mouths. The cacoshel has a penchant for healing, and will do so rapidly, before reverting to its original form.
The shel will always interrupt following any action that puts it low enough in health to transform into the cacoshel, where it will remain until it has fully healed again. The shel is a vicious predator, that will attack without any hesitation.
When the shel would fall unconscious, it instead turns into a cacoshel. At this time, it immediately heals all damage, gains the immense differentia, and permanently gains +2 Adventure, +2 Steel, +2 Armor, and +20 breakpoint.
